Thanks for the information. I reported the issue to the developers of 'igraph', which is where 'add_edges' comes from, here https://github.com/igraph/rigraph/issues/255 The response there to the question of whether it is an R core or an igraph issue was R core for sure, but probably both. Is this indeed the case for R core? To my naive eye, the error message suggests more of a known limitation, rather than a bona fide bug.
